Users frequently download new applications and associated application bundles onto their computing devices. Unfortunately, some application bundles may pose security and privacy risks to users, often due to using vulnerable third-party frameworks or having a poor transport security configuration that can be exploited by attackers. Examples of such exploitable vulnerabilities include “Zipperdown” (where attackers exploit file-naming conventions in third-party ZIP libraries to manipulate file paths for malicious payloads) and unverified user authentication schemes (where attackers inject unverified user authorization tokens into an application through an application bundle and then use the same to associate a social media account with a third-party service without the user's approval).
Unfortunately, it is typically difficult for conventional security applications installed within sandboxed operating system environments (such as IOS) to identify application bundles that pose security risks due to the sandboxed nature of the operating system. For example, the operating system may have sandbox restrictions, which may prevent applications from obtaining information about the operating system or other applications. Because applications are prevented from accessing data about other applications, security applications may be unable to scan application bundles to determine if they pose a security or privacy risk for a computing device. The instant disclosure, therefore, identifies and addresses a need for systems and methods for identifying security risks posed by application bundles.
SUMMARYAs will be described in greater detail below, the instant disclosure describes various systems and methods for identifying security risks posed by application bundles.
In one example, a method for identifying security risks posed by application bundles may include (i) intercepting, using a VPN client of a computing device, network traffic of the computing device, wherein an operating system of the computing device restricts applications into a sandboxed environment, (ii) storing, on the computing device, a copy of at least a portion of the network traffic of the computing device within a sandbox associated with the VPN client, (iii) identifying, by analyzing the copy of at least the portion of the network traffic, an application bundle within the network traffic, (iv) determining, by analyzing the application bundle in the sandbox associated with the VPN client, that the application bundle poses a security risk, and (v) in response to determining that the application bundle poses a security risk, performing a security action to remedy the security risk.
In some examples, the security action may include generating and displaying, to a user of the computing device, a notification that identifies the security risk. The security action may include at least one of preventing the computing device from downloading the application bundle or deleting the application bundle from the computing device. Analyzing the copy of the network traffic may include (i) parsing the copy of the network traffic stored in the sandbox associated with the VPN client, (ii) extracting data associated with the application bundle from the copy of the network traffic, and (iii) analyzing the data associated with the application bundle using a security policy. In some examples, the method may include presenting, based on the data associated with the application bundle, a summary of potential risks associated with the application bundle. The data associated with the application bundle may include at least one of a domain name, a declared permission requested by the application bundle, a dynamically linked library, a security setting, or a declared reason for an application executing in a background of the computing device.
In some examples, the method may include identifying, based on a uniform resource locator, a download within the network traffic that is associated with the application bundle and storing the download in the sandbox associated with the VPN client.
In one example, a system for identifying security risks posed by application bundles may include a computing device comprising at least one physical processor and physical memory comprising computer-executable instructions. Executing the computer-executable instructions may cause the computing device to (i) intercept, using a VPN client of the computing device, network traffic of the computing device, wherein an operating system of the computing device restricts applications into a sandboxed environment, (ii) store, on the computing device, a copy of at least a portion of the network traffic of the computing device within a sandbox associated with the VPN client, (iii) identify, by analyzing the copy of at least the portion of the network traffic, an application bundle within the network traffic, (iv) determine, by analyzing the application bundle in the sandbox associated with the VPN client, that the application bundle poses a security risk, and (v) in response to determining that the application bundle poses a security risk, perform a security action to remedy the security risk.
In some examples, the above-described method may be encoded as computer-readable instructions on a non-transitory computer-readable medium. For example, a computer-readable medium may include one or more computer-executable instructions that, when executed by at least one processor of a computing device, may cause the computing device to (i) intercept, using a VPN client of the computing device, network traffic of the computing device, wherein an operating system of the computing device restricts applications into a sandboxed environment, (ii) store, on the computing device, a copy of at least a portion of the network traffic of the computing device within a sandbox associated with the VPN client, (iii) identify, by analyzing the copy of at least the portion of the network traffic, an application bundle within the network traffic, (iv) determine, by analyzing the application bundle in the sandbox associated with the VPN client, that the application bundle poses a security risk, and (v) in response to determining that the application bundle poses a security risk, perform a security action to remedy the security risk.
Features from any of the above-mentioned embodiments may be used in combination with one another in accordance with the general principles described herein. These and other embodiments, features, and advantages will be more fully understood upon reading the following detailed description in conjunction with the accompanying drawings and claims.
The accompanying drawings illustrate a number of example embodiments and are a part of the specification. Together with the following description, these drawings demonstrate and explain various principles of the instant disclosure.
Throughout the drawings, identical reference characters and descriptions indicate similar, but not necessarily identical, elements. While the example embodiments described herein are susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and will be described in detail herein. However, the example embodiments described herein are not intended to be limited to the particular forms disclosed. Rather, the instant disclosure covers all modifications, equivalents, and alternatives falling within the scope of the appended claims.
DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTSThe present disclosure is generally directed to identifying security risks posed by application bundles, including by analyzing application bundles to detect possible security and/or privacy risks. Application bundles are a type of data bundle created by developers. An application bundle may be downloaded separately from an application and may store data that the application may require for operation. The application bundle may contain the application executable and any resources used by the application. Examples of the resource may include the application icon, images, localized content, and the like.
In some examples, application bundles may pose security and privacy risks on a mobile computing device by using vulnerable third-party frameworks or having a poor transport security configuration that may be exploited by an attacker. However, application bundles that pose a security or privacy risk may be difficult to identify due to sandbox restrictions of an operating system, which may prevent applications from obtaining information about the operating system or other applications. The systems and methods described herein are directed to using a VPN client to intercept all network traffic of a computing device to, for example, bypass the sandbox restrictions of the closed operating system.
In one example, and as will be described in greater detail below, an application bundle may be identified within the intercepted network traffic and analyzed to determine whether the application bundle poses a security or privacy risk. In response to determining that the application bundle poses a risk, a security action may be performed to remedy the risk, such as deleting the application bundle or displaying a notification to the user identifying the possible security and/or privacy risks posed by the application bundle. As an additional security measure, analysis of the network traffic to identify and analyze the application bundles may be performed solely on the computing device without needing to offload any of the processing to a remote service.
The following will provide, with reference to
In certain embodiments, one or more of the modules 102 in
As illustrated in
As illustrated in
As illustrated in
The example system 100 in
The computing device 202 generally represents any type or form of computing device capable of reading computer-executable instructions. For example, the computing device 202 may include an endpoint device (e.g., a mobile computing device) running one or more applications. Additional examples of the computing device 202 include, without limitation, laptops, tablets, desktops, servers, cellular phones, Personal Digital Assistants (PDAs), multimedia players, embedded systems, wearable devices (e.g., smart watches, smart glasses, etc.), smart vehicles, smart packaging (e.g., active or intelligent packaging), gaming consoles, so-called Internet-of-Things devices (e.g., smart appliances, etc.), variations or combinations of one or more of the same, and/or any other suitable computing device.
The server 206 generally represents any type or form of computing device that is capable of reading computer-executable instructions and data storage. In one example, the server 206 may include an endpoint executing an application distribution platform, which may distribute application bundles 208 to computing devices 202. Additional examples of the server 206 include, without limitation, security servers, application servers, web servers, storage servers, and/or database servers configured to run certain software applications and/or provide various security, web, storage, and/or database services. Although illustrated as a single entity in
The network 204 generally represents any medium or architecture capable of facilitating communication or data transfer. In one example, the network 204 may facilitate communication between the computing device 202 and the server 206. In this example, the network 204 may facilitate communication or data transfer using wireless and/or wired connections. Examples of network 204 include, without limitation, an intranet, a Wide Area Network (WAN), a Local Area Network (LAN), a Personal Area Network (PAN), the Internet, Power Line Communications (PLC), a cellular network (e.g., a Global System for Mobile Communications (GSM) network), portions of one or more of the same, variations or combinations of one or more of the same, or any other suitable network.
Many other devices or subsystems may be connected to the system 100 in
The term “computer-readable medium,” as used herein, generally refers to any form of device, carrier, or medium capable of storing or carrying computer-readable instructions. Examples of computer-readable media include, without limitation, transmission-type media, such as carrier waves, and non-transitory-type media, such as magnetic-storage media (e.g., hard disk drives, tape drives, and floppy disks), optical-storage media (e.g., Compact Disks (CDs), Digital Video Disks (DVDs), and BLU-RAY disks), electronic-storage media (e.g., solid-state drives and flash media), and other distribution systems.
As illustrated in
As used herein, the term “sandboxed environment” generally refers to a computing environment in which applications are isolated and restricted from accessing or obtaining information from the operating system of a computing device or other applications installed on the computing device. The sandboxed environment may prevent applications from accessing data or resources of the operating system or of other applications of the computing device 202.
The VPN module 104 may intercept any incoming or outgoing network traffic of the computing device 202. In some examples, the VPN module 104 may install a VPN client, which the VPN module 104 may direct to intercept any incoming or outgoing network traffic of the computing device 202. In some examples, the VPN module 104 may direct an existing VPN client to intercept the incoming or outgoing network traffic of the computing device 202.
At step 304, one or more of the systems described herein may store a copy of a portion of the network traffic of the computing device in a sandbox. The systems described herein may perform step 304 in any suitable manner. For example, the data management module 106 may, as part of the system 200 in
The term “sandbox” as used herein, generally refers to limited area of storage space on a computer system that isolates applications and application data from other applications and other application data. The sandbox may wrap, surround, encapsulate, monitor, and/or manage an underlying application or data. The sandbox may provide an extra layer of security that prevents harmful applications (e.g., malware) or harmful applications from negatively affecting the computer system.
In some examples, the VPN module 104 may transmit the network traffic intercepted by the VPN client to the data management module 106. The data management module 106 may scan the intercepted network traffic and may identify a uniform resource locator (URL) within the network traffic. The data management module 106 may store a copy of a portion of the network traffic containing the URL. In some example, the portion of the network traffic stored to the sandbox 126 may be determined based on a rule indicating that the portion of the traffic to be stored should include a set number of characters or words before and/or after the identified URL. In some examples, the data management module 106 may compare the URL identified in the network traffic to a safe list of URLs. In response to determining that the URL is not on the safe list, the data management module 106 may store a copy of the network traffic containing the URL to the sandbox 126 associated with the VPN client.
At step 306, one or more of the systems described herein may identify an application bundle within the network traffic. The systems described herein may perform step 306 in any suitable manner. For example, the analysis module 108, may analyze the copy of the portion of the network traffic stored in the sandbox 126 to identify an application bundle 208.
In some examples, the data management module 106 may parse the copy of the network traffic stored in the sandbox 126 associated with the VPN client. The data management module 106 may parse the copy of the network traffic and identify the URL in the copy of the network traffic. The data management module 106 may identify a download associated with an application bundle 208. For example, the data management module 106 may obtain a download using the URL and may determine that the download is an application bundle 208 associated with an application of the computing device 202. The data management module 106 may use metadata associated with the download to determine that it is an application bundle 208 and may further compare the metadata of the application bundle 208 to the applications of the computing device 202 to determine it is associated with an existing application. The data management module 106 may store the download in the sandbox 126 associated with the VPN client.
In some examples, the analysis module 108 may extract data associated with the application bundle 208 from the copy of the network traffic or the download stored in the sandbox 126 associated with the VPN client. Example of the extracted data associated with the application bundle 208 may include a domain name, a declared permission requested by the application bundle 208, a dynamically linked library, a security setting, or a declared reason for an application executing in a background of the computing device 202. The extracted data may be analyzed using one or more security policies 124 stored on the computing device 202.
In some examples, a domain name in an application bundle 208 may pose a security risk because it may be used to direct the computing device 202 to an unsecure service or server which may attempt to obtain private or sensitive information from the computing device 202. In some examples declared permissions requested by the application bundle 208 may pose security and/or privacy risks by permitting an application to obtain sensitive or personally identifying information from the computing device 202, which may be transmitted to an unsecure or risk-prone service or server. Declared permissions in an application bundle 208 may identify devices of the computing device 202 which may be initiated or used by an application to collect data, such as a camera, microphone, Bluetooth peripheral devices, GPS device, motion sensor, NFC sensor, health monitoring sensors, or the like. Additionally, the declared permissions may request that an application be permitted to access information, such as the contacts stored on the computing device 202, calendar data, reminder data, photographs, recordings, or the like.
Another example of extracted data may include declared reasons for which an application is executing in the background of the computing device 202. The declared reasons may indicate that the application is pushing silent push notifications or fetching new content. The push notifications may include sensitive or personally identifying information and may be transmitted without the knowledge or permission of the user. The new content fetched by an application may include malware, spyware, or other type of detrimental software.
Other examples of data extracted from the network traffic that may indicate potential security or privacy risks may include dynamically linked libraries and/or security settings. The dynamically linked libraries listed in an application bundle 208 may include analytics engines, vulnerable open source libraries, and the like, which may enable an attacker to access information of the computing device 202 or otherwise infiltrate or harm the computing device 202. The security settings may include application transport security policies, which may be set to permit network connections to be downgraded and thus vulnerable to attackers.
At step 308, one or more of the systems described herein may determine that the application bundle poses a security risk. The systems described herein may perform step 308 in any suitable manner. For example, the analysis module 108 may use one or more security policies 124 to determine whether the application poses a security or privacy risk. The security policy 124 may identify one or more thresholds, permissions, security settings, dynamically linked libraries, or the like, that are associated with security and/or privacy risks. The analysis module 108 may apply the security policies 124 to the extracted data associated with the application bundle 208 to determine whether the application bundle 208 is a security and/or privacy risk. The security policies 124 may be stored locally on the computing device 202.
At step 310, one or more of the systems described herein may perform a security action to remedy the security risk. The systems described herein may perform step 310 in any suitable manner. For example, the security module 110 may receive an indication from the analysis module 108 that the identified application bundle 208 poses a security and/or privacy risk. The security module 110, in response to a determination that the application bundle 208 poses a security risk, may perform a security action to remedy the risk. Examples of the security action may include preventing the computing device 202 from downloading the application bundle 208 and/or deleting the application bundle 208 from the computing device 202.
In some examples, the security module 110 may generate and display a notification that identifies the security and/or privacy risks posed by the application bundle 208. The notification may be a summary of potential risks associated with the application bundle 208 based on the analyzed data associated with the application bundle 208. In some examples, the notification may include a recommended course of action to remedy the possible security risk. For example, the recommendation may be do delete the application bundle 208 from the computing device 202. The notification may include a link or button asking the user to confirm or ignore the recommended course of action. The security module 110 may receive an indication from the user to delete the identified application bundle 208 via the link or button displayed in the notification. The security module 110, in response to receiving the indication, may delete the application bundle 208 from the computing device 202. In some examples, the recommended course of action displayed in the notification may include detailed instructions informing the user how to manually remove the identified application bundle 208.
The systems and methods described herein are directed to providing identifying and remedying application bundles that pose a security and/or privacy risk. Application bundles may pose security and privacy risks on a mobile computing device by using vulnerable third-party frameworks or having a poor transport security configuration that may be exploited by an attacker. However, application bundles that pose a security or privacy risk may be difficult to identify due to sandbox restrictions of an operating system, which may prevent applications from obtaining information about the operating system or other applications. The systems and methods described herein are directed to using a VPN client to intercept all network traffic of a computing device, identifying an application bundle within the network traffic, and analyzing the identified application bundle to determine whether the application bundle poses a security or privacy risk. In response to determining that the application bundle poses a risk, a security action may be performed to remedy the risk.
